CURTIS HOLLAND, OF MILLIS, MASSACHUSETTS.

SKATE-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 484,201, dated October 11, 1892.

Application filed July 1, 1892- Serial No. 438,642. (No model.)

To all whom 21,25 may concern.-

Be it known that I, CURTIS HOLLAND, of

Millis, county of Norfolk, State of Massachw' setts, have invented an Improvement in Skate- Sharpeners, of which the following description, in connection with the accompanying drawings, is a specification,like letters on the drawings representing like parts.

This invention has for its object to improve, simplify, and cheapen the construction of devices for sharpening skates.

In accordance with this invention a bar of suitable length tobe grasped by both hands is provided on its under side at a point about midway between its ends with a transverse slot or recess, the bottom of which is dovetailed, and a file, having a conveXed or other acting surface and of suitable shape in crosssection to fit the dovetailed portion of the bottom of said' transverse slot or recess, is held therein by a set-screw, which passes down through the bar and engages the back of the file. The transverse slot or recess is made of suitable width to receive a skaterunner and serves as aguide when the bar is moved from end to end of said runner, and the file contained in and forming the bottom of said recess lies in parallelism therewith, so that as the bar is moved from end to end of the skaterunner the file will be utilized in the direction of the length.

Figure 1 shows in front elevation a skatesharpening device embodying this invention; Fig. 2, across-section of the implement shown in Fig. 1, taken on the dotted line 0000; Fig. 3, an end view of the files which may be used; and Fig. 4 shows the implement in operative position on a skate-runner.

The bar a, of suitable shape and length to be grasped andoperated by both hands,is made of any suitable material, as wood or metal, and has formed on its underside at a point about midway between its ends a transverse slot or recess b of a width sufficient to receive the skate-runner, and as said skate-runners vary slightly in width it may be made sufficiently wide to receive any ordinary runner. The

bottom of the transverse slot or recess 2) is dovetailed, as shown, to receive a filed, made to fit it. The file dhas a convexed, or it may be a fiat-acting, surface, (see Fig. 3,) and is held in place in the dovetailed portion of the recess by a set-screw c, which passes down through the top of the bar a and engages the back of the file.

To sharpen the skate-runner, the file is placed in the slot or recess 1), lying in parallelism therewith, and the bar a is. then moved from end to end of the skate, the said slot or recess serving as the guide. By forming the slot or recess 11 at right angles to the bar a, or transversely, as stated, I am enabled to place a file therein and use it in the direction of its length. In other words, the bar a, which serves as the hand-piece, is at right angles to the file and to the runner-receiving recess which containsit. Itis obvious,however, that the skate may be held in numerous ways while the de-' vice is being operated, and also that the device may be operated in numerous ways, so that I do not desire to confine my invention to any particular way of using the device, so long as it is constructed as shown and described.

I claim The bar a, of suitable length tobe engaged by both hands, having in its under side at a point midway between its ends a transverse slot or recess 1) of suitable width to receive the skate-runner and dovetailed at the bottom, combined with a file shaped in cross-section to fit said dovetailed portion of the recess, thereby lying in parallelism with and forming the bottom of said recess, and the set-screw c, passing down through the handpiece and engaging the back of the file, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CURTIS HOLLAND.
